Logitech G604 Lightspeed Wireless Gaming MouseCarbon Neutral Certified by SCS Global Services

I always come back to this mouse. The main things I love are:1. Wireless with both dongle and Bluetooth - makes it easier to share between computer2. Uses AA battery so I can use a good one and it lasts a lot3. Enough programmable buttons4. SIDE SCROLL BUTTONS#4 is my favorite. It's a small thing but I have become so used to having those side-clicks that I only get mice with them and a lot of the popular ones don't have it or if they do they are wired. For some reason Logitech decided on discontinuing the G604 so I recommend either get one now or start saving because they will become more expensive with time.

I've been using this brand/model mouse for several years. I just replaced my 2nd G604 after 2 years (warrantied) with the same exact model. I can't imagine ever using another one - this model works so well.I definitely recommend this mouse.

This is the best wireless gaming mouse on the market period. I don't understand why more companies don't add this many buttons to all of them. They are all easy to hit and with g hub are all customizable. The mouse fits great in most hands (my friends and I all use it). It doesn’t have as many buttons as a mouse for an mmo. But for shooters, or most gaming it’s perfect. Could set up different customizations for each game and computer software if needed. Don’t understand why they haven’t made a rechargeable version.

Love the LiteSpeed series of Logitech mice, as I've had a few. This newest one, the G604 is amazing! Tracks on any surface, lift-off is great, no noticeable lag between the usb wireless or the bluetooth (an that is a plus for me to use on my main computer an laptop without having to swap a dongle), single AA battery life is well on par with spec, an the USB dongle is as tiny as you could make one, an even has a place under the palm-wrest to put it whilst traveling an throwing it into a laptop bag, which is why I got this in the first place!If there is a VERY slight niggle on my part, is the lack of a pinky rest on the right side. My right pinky is left to drag on the surface. I feel this would have been a no-brainer were the whole mouse wider.Another thing I whish Logitech would bring back is the way the switchable wheel clicks are used. In the past, you double-clicked the scroll wheel to make it either free-spinning, or with the clicks. With this one, there is a button underneath that would, IMO, be better served as a macro button.Can't think of much else without comparing to dedicated "gaming" mice. The 6 side buttons are in a great position for me, even more than my last 3 iterations of the Razer Naga series or the Corsair MMO mouse. Logitech just get's it done every time, though a bit slow to respond to the market. You can't go wrong.

Updated Review: Finally figured out how to ulitze the on-board memory so not to have the GHub software running in the background. Unfortunately, I'm leaving my rating at 4-stars as this feature is NOT outlined anywhere in the product manual. Had to perform various searches in Logitech's community forum. It is not a clean and clear process...and the software to turn-on the on-board memory feature is a separate download. In addition to that, messages displayed during enabling this feature is confusing and murky at best. After several attempts I think I finally got working.Finally, the G604 is not as comfortable in my smaller sized hands (even though it's smaller than the G602) after prolonged use. BRING BACK THE G602 SO I WON'T HAVE TO PAY OVER $120 TO BUY ONE NEW!!!!!!Why Logitech screwed up the whole process of using the on-board memory feature in their new product is beyond me. Why couldn't they just leave the whole process clean and simple like they had it with the G602!!!???????????I didn't expect another G602 experience, although, I hoped. This does the job as needed a programmable wireless mouse within a reasonable price range for work. The biggest let down is the fact that this mouse does not have on-board memory to retain settings for the buttons like the G602. You have to have the GHub software actively running in order to use the programmed buttons. Unfortunately, the lowest price for a G602 I've seen is still over $120. I wish manufacturers would STOP messing with a good thing, like the G602, in order to "improve" a product line. I do hope Logitech decides start manufacturing the G602 again, or market a programmable mouse with on-board memory to obviate the need to have their software running in order use a product's programmable features!!!

This is my third or fourth mouse of this model. Only reason I've gone through so many over the years is because I play wow a lot and wear out the left click button. I'm sure it's an easy enough fix but I honestly can't be bothered so I just buy a new one. Been using this since the g602. The battery life on Bluetooth lasts me for MONTHS. I'll be sad when I can't get this mouse anymore. It's legit best on the market

Had to replace it within a year due to the infamous double click issue that's been going on with logitech mice for years. Gave them the benefit of the doubt when I bought this as a replacement as my previous logitech mouse lasted for many years without this issue.

if youre looking for a replacement of the g602 this is definitely it, it more or less feels the same and hooking this mouse up automatically differed to all my custom g602 settings which is awesome.havent had the mouse long enough for any flaws or breakdowns but i always update my reviews when something goes out and how long it lasted so if you dont see an edit with a date assume its still kicking. that said this thing is more or less the g602 just slightly lighter and the two pointer clicks on the left clicker being slightly closer
